Dahlia plant named ‘Baldadenyel’

ABSTRACT

A new and distinct cultivar of  Dahlia  plant named ‘Baldadenyel’, characterized by its double-type, medium yellow colored inflorescences, dark green-colored foliage, and vigorous, upright-mounded growth habit, is disclosed.

Latin name of genus and species of plant claimed: Dahlia variabilis.

Variety denomination: ‘Baldadenyel’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahliaplant botanically known as Dahlia variabilis and hereinafter referred toby the cultivar name ‘Baldadenyel’.

The new cultivar originated in a controlled breeding program in Hem, TheNetherlands during August 2015. The objective of the breeding programwas the development of Dahlia cultivars that are freely flowering withlarge inflorescences, mid-season flower timing, and a vigorous,upright-mounded growth habit.

The new Dahlia cultivar is the result of open pollination. The female(seed) parent of the new cultivar is the proprietary Dahlia variabilisbreeding selection coded D16-226-1, not patented, characterized by itsdouble type, light yellow-colored inflorescences, medium green-coloredfoliage, and moderately vigorous, upright-mounded growth habit. The male(pollen) parent of the new cultivar is unknown. The new cultivar wasdiscovered as a single flowering plant within the progeny of the abovestated open pollination during July 2016 in a controlled environment inHem, The Netherlands.

Asexual reproduction of the new cultivar by terminal stem cuttings sinceJuly 2016 in Hem, The Netherlands and Andijk, The Netherlands hasdemonstrated that the new cultivar reproduces true-to-type with all thecharacteristics, as herein described, firmly fixed and retained throughsuccessive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedlyobserved and can be used to distinguish ‘Baldadenyel’ as a new anddistinct cultivar of Dahlia plant:

-   -   1. Double-type, medium yellow colored inflorescences;    -   2. Dark green-colored foliage; and    -   3. Vigorous, upright-mounded growth habit.

Plants of the new cultivar differ from plants of the female parentprimarily in having darker yellow colored inflorescences.

Of the many commercially available Dahlia cultivars, the most similar incomparison to the new cultivar is HYPNOTICA Yellow ‘Dodahhypnoyel 19’,U.S. Plant Pat. No. 31,761. However, in comparison, plants of the newcultivar differ from plants of ‘Dodahhypnoyel 19’ in at least thefollowing characteristics:

-   -   1. Plants of the new cultivar have slightly darker yellow        colored inflorescences than plants of ‘Dodahhypnoyel 19’;    -   2. Plants of the new cultivar have larger diameter        inflorescences than plants of ‘Dodahhypnoyel 19’; and    -   3. Plants of the new cultivar have higher growth vigor than        plants of ‘Dodahhypnoyel 19’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonablypossible to make the same in color illustrations of this type, typicalflower and foliage characteristics of the new cultivar. Colors in thephotographs differ slightly from the color values cited in the detaileddescription, which accurately describes the colors of ‘Baldadenyel’. The14-week-old plants were grown in 6.5-inch pots for 10 weeks in aglass-covered greenhouse in Hem, The Netherlands. Plants were given onepinch before transplant.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmentalconditions to date. Accordingly, it is possible that the phenotype mayvary somewhat with variations in the environment, such as temperature,light intensity, and day length, without, however, any variance ingenotype.

The chart used in the identification of colors described herein is TheRHS Colour Chart of The Royal Horticultural Society, London, England,2015 edition, except where general color terms of ordinary significanceare used. The color values were determined in March 2021 under naturallight conditions in Boskoop, The Netherlands.

The following descriptions and measurements describe 14-week-old plantsproduced from cuttings from stock plants and grown in a glass-coveredgreenhouse under conditions comparable to those used in commercialpractice. The plants were grown in Hem, The Netherlands in 6.5-inch potsfor 10 weeks utilizing a soilless growth medium. Plants were given onepinch before transplant. Three Daminozide treatments were applied: oneat 2,500 ppm two weeks after transplant, a second at 3,000 ppm fourweeks after transplant and a third at 3,500 ppm six weeks aftertransplant. Greenhouse temperatures were maintained at an average ofapproximately 64° F. (18° C.) during the day and approximately 61° F.(16° C.) during the night. Supplemental lighting was used. Measurementsand numerical values represent averages of typical plants. #
